Objective To analyze the effectiveness of a tele-diet combined exercise intervention program in elderly patients with type 2 diabetes mellitus combined with sarcopenia. Methods The selection of 80 cases of elderly patients with type 2 diabetes mellitus combined with sarcopenia was conducted from December 2022 to February 2023 in 2 communities in Urumqi City,and the 2 communities were randomly divided into an experimental group and a control group,with 40 cases in each group. The experimental group carried out the intervention of dietary combined with exercise through tele-technology on the basis of the routine health education,and the control group implemented the routine health education. The scores of somatic functions,muscle strength and quality of life of patients with sarcopenia were compared between the 2 groups before and after the intervention.
